Bulk scheduling? How to schedule a client one time for multiple days of a particular event type?

I have clients who I book multiple sessions with at a time. (Examples: Clients I meet weekly, at the same day/time each week for several weeks in a row; Clients that I need to bulk schedule several meetings for on different days/times for a project [of a particular event type]; Self-booking clients who have paid for a certain number of sessions; etc.)

How can I do this in one action, and not have to go through the whole scheduling process over, and over, and over each time I need to schedule the same client for multiple meetings? 

Thank you!
